<p>The exclusion of scripts, applets, and other multimedia elements reduces the risk of exposure to harmful or malicious objects caused by inclusion of XHTML content. Because of security concerns related to images, an implementation MAY choose not to show images but instead show only the 'alt' text. Because of security concerns related to hyperlinks, an implementation MAY choose not to make them clickable.</p>
<p>The exclusion of scripts, applets, and other multimedia elements reduces the risk of exposure to harmful or malicious objects caused by inclusion of XHTML content. In order to reduce the risk of so-called "phishing" attacks, an implementation MAY choose not to make hyperlinks clickable. Because images served on the Internet may contain malicious instructions or software code and may enable the entity serving the image to determine the network availability of the requesting entity, an implementation MAY choose not to show images but instead show only the 'alt' text or to not fetch images offered by entities that are not authorized to view the user's presence.</p>
